To furthermore add on, I think the above bbfas talked about spread and what have you, is it because UOB has thinner spread?
from UOB website now sell PAMP 1 oz bar is $2,629 and buyback is $2,533. Meaning if you buy and sell back immediately, bank earns $96
compear to Gold Silver Central sell $2,668 and buy back is $2,523, they earn $145 immediately if you buy and sell back immediately

now that I do this simple home work, buy from UOB main branch better
but however, the prices quoted above are spot prices and can change in milliseconds
disclaimer: do not believe in what I say thanks
